NOMINATION RATIONALE
1) BEST API AND PARTNER APPS MARKETPLACE
Klaviyo’s developer portal is more than just a technical resource – it’s a partner enablement hub designed to support both developers and business decision-makers with clearly communicated APIs, use case driven content, and intuitive navigation. The Partner Resources section (accessible directly from the side navigation) offers a guided journey from inspiration to App Marketplace launch. It starts with high-level content on what makes a Klaviyo app successful, giving partners a clear picture of the benefits of building with Klaviyo and how integrated data can drive customer value.
